    3. Saline compounds might be decomposed, so as to produce colors on paper. T//e second and tliird projects were finally adopted for a future trial, since they could be made to furnish permanent records. Here we have stated by Dr. Jackson, the projects to be experi- mented upon, as represented to Prof. Silliman ; and thus far, or at least in reference to the third project, Dr. Jackson and Prof. Morse agree. But in reference to the Electro Magnetic Telegraph, Morse's real, practical invention, they are wide as the poles asunder. Dr. Jackson asserts that he described it minutely to Prof. Morse on board the Sully, while Prof. Morse asserts that he never re- ceived from Dr. Jackson a practical hint on'the subject. Dr. Jackson himself shall be the witness to prove that it was not an Electro Magnetic Telegraph that he had in view in his conversation with Prof. Morse on board the Sully. 1. In his letter to Prof. Silliman, dated December 25th, 1832, he says that the telegraph invented by him and Prof. Morse, jointly, was an Electric. Telegraph 2. In his letter to Prof. Morse, dated November 7th, 1837, the two projects which he says were finally adopted for a future trial, were projects of an Electric Telegraph merely, and had nothing to do with electro magnetism. Nor does he in that let- ter, pretend that he had with Prof. Morse, on boaid the Sully^any conversation about an Electro Magnetic Telegraph; and yet,two years afterwards, he twice stated that he had in that letter, reca- pitulated all the conversation he had with Prof. Morse on board the Sully, having relation to the telegraph. In an article prepared by Dr. Jackson, and published in the Boston Morning Post in January, 1839, it is represented that this letter contained a detail of all the circumstances of /he invention and of the conversation which took place on board the Sully. In a letter to Sidney E. Morse, brother of Prof. Morse, dated * January 23d, 1839, Dr. Jackson, speaking in reference to the same letter, said: '7 wrote a letter in wheh all our conversation which look place on board ship, was recapitulated, so that he (Prof. Morse) jp in full possession of the facts on which my claim is founded. Nor can Dr. Jackson now claim that any thing material vva» omitted in that letter; for he says therein, you (Morse) say that you. have a distinct recollection of the manner, time, and place, and the moment when the thought of making an electric wire the means of communicating intelligence first came into your mind andI was uttered. If you have this vivid recollection, you cannot refuse your assent to the following remarks; for I remem- ber too, and am happily endowed with a strong and retentive memory as to the facts.
